Abstract

Various solutions for frequency hopping design for grant-free transmission with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive a frequency hopping pattern from a network node. The apparatus may determine a frequency hopping location according to the frequency hopping pattern. The apparatus may perform an uplink grant-free transmission according to the frequency hopping position. The frequency hopping pattern may comprise user equipment specific information.

       1. A method, comprising:
 receiving, by a processor of an apparatus, a frequency hopping pattern from a network node; 
 determining, by the processor, a frequency hopping location according to the frequency hopping pattern; and 
 performing, by the processor, an uplink grant-free transmission according to the frequency hopping position, 
 wherein the frequency hopping pattern comprises user equipment (UE) specific information, and 
 wherein the UE specific information comprises a UE identity (ID), or a group UE ID. 
 
     
     
       2. The method of  claim 1 , wherein the frequency hopping pattern comprises at least one of a random frequency hopping pattern, a fixed frequency hopping pattern, an orthogonal frequency hopping pattern, or a quasi-orthogonal frequency hopping pattern.
